Re: Tips for daily driver mods 72 Cheyenne

Another So Cal neighbor here. Very nice truck. I would install a Pertronix Ignitor if it still has points and install a 4L80E or a 4L65E trans for the OD. I'm just not a fan of the 700R4 trans anymore. I have one waiting for my truck (someday) and I just installed one this week in a 71 C20 with a 350 and 4:10's. The owner complained of it just revving too high on the freeway and now in 4th with the converter locked it just cruises. I've driven mine to Vegas and I have 3.54's and a TH400. 70-75 no problem, but I'd like to get a little more than 12 mpg. I think the 4L80, newer cam profile (still stock idle) and a 4bbl style fuel injection will get me 16-18mpg. I was able to get almost 19mpg from my old 66 Chevelle. It had a 383 with a 750 double pumper and a 700R4 and 3:36 gears. Total freeway cruiser. It's all in the tune.
